I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Overview: This project demonstrates a comprehensive Arduino-based RFID door lock system designed for secure access control. Utilizing the MFRC522 RFID reader module, a servo motor for door mechanism ...

This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seemed to know ...

If you can dream it, Arduino can help you build it -- perhaps with a dash of MakerBot thrown in for good measure. The latest homebrew project to hit the ol' inbox sounds an alarm whenever you leave a ...

Instructables user talk2bruce created the Arduino Internet Gizmo, a card reader that takes you to your favorite websites with a touch of an RFID tag. Instructables user talk2bruce created the Arduino ...

To let its employees socialize from 300 miles away, ad agency Allen & Gerritsen hacked together an interactive game using RFID sensors, an Arduino, and some custom in-house development. Now company ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got the ...
